Goal: This course helps the students in understanding a powerful, portable and flexible structured programming

language which is suitable for both systems and applications programming. It is a robust language which contains

a rich set of built-in functions and operators to write any complex program.

Objectives:

The course should enable the students to:

I. Develop modular, efficient and readable C programs by hands-on experience.

II. Interpret good profound knowledge in C programming language and enable them to build programs using operators,

control structures, arrays, strings, functions, pointers and structures to solve the real world problems.

III. Illustrate memory allocation to variables dynamically and perform operations on text and binary files.

IV. Develop interest and lay foundation to learn data structures and Java programming languages and excel as a

professional programmer.
